Recover dangling blobs in Git

Question

I did a "git rm -rf ." (trying to purge the cache of files I had removed after doing "git add .") without thinking git would physically delete the files. I don't have an initial commit/branch yet.

$ git init
$ git add .

I remember to add my ".gitignore". Then, out of being lazy and also not bothering to look up the proper command I did:

$ git rm -rf .

Now every file that git was tracking is gone. Oops.

How do I recover the files using the dangling blobs

$ git fsck

Looking around I could only find tutorials on recovering dangling commits.

Answer 1

You can use git show fce4a77b63b25abbc010859b4037589983820329to see the content (or git show fce4a > somefile to dump it to a file).

File names are lost (unless there are also dangling trees or other sources of information like command history in .bash_history).

If you can see (with git ls-tree) your root tree, you can create a commit with it using git commit-tree command or some git checkout e48751c3b37a9cab692133202bbb933241f73f69 -- . to retrieve files.
